PCDOE Practice Question: Bootstrapping a Google Cloud organization for DevOps
This PCDOE practice question tests your understanding of bootstrapping a google cloud organization for devops. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are required steps to set up a shared VPC for DevOps teams?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Attach the service projects to the host project.
Option A is correct because attaching service projects to the host project is a mandatory step in Shared VPC setup. After designating the host project and enabling Shared VPC, you must attach each service project to the host project so that the service projects can consume subnets from the host project's VPC. Without this attachment, the service projects cannot use the shared networking resources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Attach the service projects to the host project.
Why this is correct
Service projects must be explicitly attached to use the shared VPC.

✗
Create a new VPC in the service project and peer it with the host project.
Why it's wrong here
Shared VPC uses the host project's VPC directly; peering is not required.
✗
Configure Cloud Interconnect between the host and service projects.
Why it's wrong here
Cloud Interconnect is for on-premises connectivity, not needed for shared VPC.
✓
Designate the host project and enable Shared VPC for it.
Why this is correct
This is the initial step to set up shared VPC.

✗
Grant the Shared VPC Admin role (roles/compute.xpnAdmin) to the service project team.
Why it's wrong here
This role is for managing the host project, but it's not a step to set up shared VPC.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that Shared VPC requires VPC peering or that service projects need their own VPC, but the correct model is a single host project VPC shared via attachment, not peering.
Detailed technical explanation
How to think about this question
Shared VPC uses the concept of a host project that owns the VPC network and subnets, while service projects are attached to consume those subnets. Under the hood, Google Cloud uses the XPN (Cross-Project Networking) API to manage resource sharing, and the attachment creates a binding that allows service project resources (e.g., Compute Engine instances) to use host project subnets. A real-world scenario is a large organization with multiple DevOps teams where the network team manages the host project and grants subnet-level IAM roles (e.g., roles/compute.networkUser) to service project principals, ensuring least privilege.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
